Abstract

The device includes a drop dispenser orifice formed in a dispenser end, and a mechanism for visually locating the orifice, by forming a demarcation zone having a color that contrasts strongly with other portions of the dispenser end.

First claim

The invention claimed is:

1. A dispenser device for dispensing liquid in the form of drops, comprising:
a dispenser end;
a drop dispenser valve formed of a piece of elastomer material, the drop dispenser valve operable between a liquid-passing configuration and a liquid-blocking configuration;
a drop dispenser orifice formed in a distal end of the drop dispenser valve including a drop-forming cavity inside the drop dispenser orifice, wherein the drop-forming cavity has a conical shape that flares outwardly and having an inner conical surface;
a support;
the dispenser end including a cap for pressing the drop dispenser valve against the support, the cap having an end surface in the shape of a substantially-flat disk with a central hole, the drop dispenser valve extending at least partially through the central hole with the drop dispenser orifice located adjacent to the end surface; and
an element for visually locating the drop dispenser orifice, the element including a demarcation zone having a color that contrasts with the cap, the demarcation zone obtained by coloring the inner conical surface of the drop-forming cavity inside the drop dispenser orifice.

2. The device according to claim 1 , including a dispenser endpiece cylindrical in shape.

3. The device according to claim 1 , wherein the disk is of opaque color.

4. The device according to claim 1 , wherein the demarcation zone is formed by silk-screen printing, pad printing, hot marking, printing by inkjet, or laser marking.

5. The device according to claim 1 , the dispenser device being configured for dispensing liquid in an eye.

6. A method of manufacturing a device according to claim 1 , said method including a marking step in order to form the demarcation zone, the marking step including one of a step of silk-screen printing, pad printing, hot marking, printing by inkjet, or laser marking.

7. The device according to claim 1 , inside the drop-forming cavity being different in color relative to the other portions of the dispenser end.

8. The device according to claim 1 , wherein the cap is white.

9. The device according to claim 1 , wherein the drop-forming cavity is different in color relative to the cap.
